[%c_highlight c2;keyPressed;none;opacity;0.8;square;c2;persistent;false,c3;keyPressed;none;opacity;0.8;square;c3;persistent;false] A curious square for the knight, since the more traditional laws of strategy don't recommend a knight in front of the c-pawn in queen's pawn structures. However, this rule has been broken for many years, and its validity is even more questionable in fast time controls.
